2019-03-04kbuild: update comment block of scripts/clang-version.shMasahiro Yamada1-7/+3
Commit 469cb7376c06 ("kconfig: add CC_IS_CLANG and CLANG_VERSION") changed the code, but missed to update the comment block. The -p option was gone, and the output is 5-digit (or 6-digit when Clang 10 is released). Update the comment now. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2018-08-22kbuild: Add a space after `!` to prevent parsing as file patternMichael Forney1-1/+1
Some shells use !(pattern|...|pattern) to match file names not containing the specified patterns. This may result in output like $ ./scripts/clang-version.sh gcc ./scripts/clang-version.sh[18]: COPYING: not found printf: %d __clang_major__: conversion error printf: %d __clang_minor__: conversion error printf: %d __clang_patchlevel__: conversion error 00000 $ and set CONFIG_CLANG_VERSION to the invalid value '00000'. POSIX says[0] If the pipeline begins with the reserved word ! and command1 is a subshell command, the application shall ensure that the ( operator at the beginning of command1 is separated from the ! by one or more <blank> characters. The behavior of the reserved word ! immediately followed by the ( operator is unspecified. So, just add a <blank> to prevent this.
